Moving and rotating the reference system origin of the site

The following options have been added to the "Project" group in the application toolbar:

• Move the reference system of the site
  Allows users to define a new position for the reference system origin of the site on the workspace. 
• Rotate the reference system of the site
  Allows users to specify an angle on the workspace to rotate the reference system of the site. 

Thanks to these tools, the origin and orientation of the reference system of the site can now be defined graphically.
